Convex Self-Hosting FAQs

Question 1

How does self-hosting affect Convex Auth setup?

Accepted Answer

The automated CLI auth setup is Cloud-only. Self-hosting requires manual generation of RSA keys in PKCS#8 format and explicit configuration of JWKS and JWT_ISSUER variables.

Question 2

Which database is recommended for self-hosted Convex?

Accepted Answer

PostgreSQL is the required database. For best compatibility, you should use the POSTGRES_URL environment variable and ensure a database named 'convex_self_hosted' is created.

Question 3

What platforms are supported for deployment?

Accepted Answer

While it can run anywhere with Docker, this skill includes specific guidance for Fly.io, Railway, AWS (EC2/SST), and Coder workspaces.

Question 4

What are the limitations of the Convex CLI for self-hosted instances?

Accepted Answer

The Convex CLI is primarily optimized for Convex Cloud. Many commands lack native support for self-hosted backends, requiring manual environment configuration and API interactions which this skill provides.

Question 5

Can I scale a self-hosted Convex instance horizontally?

Accepted Answer

By default, the self-hosted version is single-node. Horizontal scaling currently requires modifications to the Rust codebase or specific infrastructure configurations detailed in this skill.
